I have version 1.51 Civa INS installed within FS2004 along with my Tinmouse 737-200 aircraft.When I set the INS system up ready for operation prior to moving the aircraft all seems well, (Aligning, setting to Nav, entering waypoints, etc.), I have waypoints ready to follow which have been entered and checked, after take off, when I click on the "Nav" button (Rad/Nav") on the main panel to couple the INS system to the auto pilot, with the auto pilot B "on" and with heading mode selected, and while on a heading providing a very low cross track error "XTR/TKE" (0.9 or less), the INS waypoint is not captured and I continue to stay in heading mode. Any suggestions what might be wrong, or what I need to do?Thanks for any help with this question.

The Sperry 77 will stay in heading mode...the INS makes its inputs to the AFCS by slewing the heading bug.Make sure that after entering NAV mode you have entered an active leg, normally "WYPT CHG" then "1" then "2" then "INSERT" to activate a leg from waypoint 1 to waypoint 2. If the INS is in "AUTO" the active legs will switch automatically at waypoint passage.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Thank you for your reply to this topic, I did make sure your directions where followed, sadly the same problem persists.When I set the selection from "Rad" to "Nav" with the auto pilot on and in heading mode etc. the heading bug remains in its previously selected position, and I am still able to alter the heading bug as in "Rad" mode and the aircraft follows any alteration to my heading as if still in "Rad" mode. It seems that the INS system is not connecting to drive the heading bug.Maybe if you are able to send be the parts of the aircraft.cfg and/or panel.cfg that effect this aspect of the simulation, I could copy and paste it into my panel.cfg and/or aircraft.cfg and give that a try. My tinmouse has the reality xp weather radar and the "ilh_tcas_v4" installed and working fine.Thank you for your continued help in this regard.

Make sure that you have v1.24 of the panel gauge...the earlier versions will not work with the new (v1.50 and later) versions of the CIVA INS unit.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Thank you for your advice, can I ask how do I check which version of the panel gauge I have? The reason I ask is of interest for another reason aswell as the one you mention, with regard to the "performance data Calcuation system". When I validate the "pdcs" (page 3) system and then enter a figure in to the temperature field and activate the take off thrust calculation I always get the default epr of 1.52 which can be activated and the bugs on the epf fauge do move to indicate this selection.The epf remains the same (1.52) when I select climb thrust. It seems that the calculation is not being made.This part of the panel I know should provide variable epr settings, maybe it is a problem with my panel gauge.All other aspects of the panel seem to be working well. any ideas?Thank you for your continued help with my Tinmouse 737-200 panel issues.

Found a more recent gauge (from "version2 panel" download from flightsim.com), after adding this all seems well with tinmouse panel.Thanks for the help.
